The Little Ice Age was a period of global cooling that occurred from the 13th to the 19th centuries. This cooling was likely caused by a number of factors, including unusual solar activity and volcanic eruptions. The Little Ice Age greatly impacted h...uman social orders, especially during the 17th century. When the climate changed, and weather became unpredictable, the world changed profoundly. Poor harvests led to hunger, which led to even less productivity, which even resulted in violent upheaval in a lot of places. All this from a little change in the temperature? Definitely.

This video shows how the next Ice Age could start and its impact on the Earth. Very well done with excellent graphics. A good way to explore the impact of global warming. Not for younger students. Shows impact of freezing on humans, too.

From extreme weather to threatened ways of life, the effects of climate change are real, and they are happening right now around the globe. As the Earth warms, the atmosphere contains more energy and moisture. These drive extreme weather, such as cri...ppling heat waves, heavier rains and more powerful hurricanes. It even causes severe drought in some places -- because a warming Earth increases evaporation, too, drying out some places and causing a lot more dust and particles to get in the air. In the mountains of the American West, warming temperatures are already having a big effect on the delicate balance of life. (2:30)[more]

Science columnist Lee Hotz describes a remarkable project at WAIS
Divide, Antarctica, where a hardy team are drilling into
ten-thousand-year-old ice to extract vital data on our changing climate.
Robert Lee Hotz is the science columnist for the ...Wall Street Journal,
where he writes about cutting-edge research on climate change,
cosmology, molecular medicine, the human brain and much more . He has traveled three times to the South Pole. (09:46)[more]

We already know that rapid climate change is happening, but how bad could it get? The answer lies with us, human beings. That's because the decisions we make now will determine if the effects of rapid climate change are mild or extreme. Scientists wh...o study the climate tell us that if we continue to add carbon to the atmosphere at the current rate, the Earth will get a lot warmer in the coming years and decades. They use big, brainy computers to simulate what the climate will look like in the future. (2:30)[more]
